Allow portfolios to be visually compared with the performance of assets from imported data. Example a forex portfolio compared to an imported data set of the S&P 500 over the same period of time. This would allow you to show stats like net % increase etc.
This feature was available in Quant Analyzer. I am suggesting porting this to SQX and build out higher level functionality
